ELBOW FOR STOVEPIPES.

SPECIFICATION forming part of Letters Patent No. 627,633, dated June 27,1899. Application filed December 31, 1898. Serial No. 700,858. .(Nomodel.)

To all whom it may concern.-

Be itknown that I,UR BANAD. ALEXANDER, a citizen of the United States,residing at Cannonsburg, in the county of WVashington and State ofPennsylvania, have invented certain new and useful Improvements inElbows for Stovepipes; and I do hereby declare the following to be afull, clear, and exact description of the invention,such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to elbows, and particularly to elbows used forstovepipes; and the particular object of the invention is to constructthe elbow in such shape or form as to admit of its being opened orunfolded for convenience in packing and shipping.

The invention combines simplicity, efficiency, and durability, and is,further, cheap to manufacture.

The invention consists in certain novel features and details ofconstruction, as will be hereinafter described, and finally pointed out'in the claim.

In the drawings, Figure l is a side elevation of an elbow embodying my;invention, the device being shownin its closed or normal position readyfor use. Fig. 2 is a similar view, the elbow being opened into theposition for convenience in packing. Fig. 3 is a central verticalsectional view showing more clearly the manner in' which the differentparts or sections are secured together. Fig. 4 is a perspective view ofthe elbow shown in the open position, and Fig. 5 is a similar view ofseveral elbows nested.

Similar letters of reference indicate corresponding parts in thedifferent figures'of the drawings.

I will now describe my invention, which is constructed as follows:

The elbow is formed of five distinct pieces a, b, c, d, and e, which aresecured together in such a manner as to form two independent sections Aand B. These sectionsA and. B are hinged or pivoted together at oneoftheir ends, as shown at f, the purpose of which is to admit saidsections A and B to be opened without becoming entirely separated. Thepivots also serve to hold said sections in a rigid position at thispoint when the device is in use.

The section A is formed of three parts a, b, and c, the part I) beingprovided with flanges h, which overlap the parts a and c. Said parts aresecured together by rivets or in any each other, or both sections may bestamped out in one piece each and formed intothe proper shape bysuitable machinery.

The section B of the elbow is provided with tongues g for engaging theouter end of the section A and holding it in its normal position when inuse.

Theoperation of my invention is as follows: Assuming the device to be inits normal position and it is desired to prepare it for shipment, allthat is necessary to do is to grasp the two sections A and B at theopposite ends from the hinge or rivets and pull them into the openposition, as shown in Fig. 2. When in this position, they are in aposition to be packed one within .the other. It will be readily seenthat a greater number of elbows made after my invention can be packed ina much smaller space than can be done with the class of elbows now inuse. When the elbows have reached their destination, they are removedfrom the package and closed, after which they are ready for use.

Having described my invention, what I claim is- A stovepipe-elbowconsisting of two longitudinal sections pivotally connected together andadapted to be swung longitudinally in relation to each other whereby thesections may be brought into operative relation or moved from suchrelation for the purpose of nesting the elbows, substantially as shownand described.

In testimonythat I claim the foregoing as .niy own invention I havehereunto set my hand,.in the presence of two witnesses, at

Cannonsburg, in the county of Washington and State of Pennsylvania, this27th day of December, A. D. 1898.
